THRESHING-IVIACHINE.

Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed December 13, 1901. Serial No. 85,818.

To all whom, it may concern:

Be it known that I, FRANK F. LANDIs, a citizen of the United States, residing at l/Vaynesboro, in the county of Franklin and State of Pennsylvania, have invented certain new and useful `Improvements in Threshing- Machines, of which the following is a specification.

In the use of pneumatic straw-stackers with threshing machines as usually constructed and arranged the chaff, beards, dust, and all fine dirt and filth are discharged with the straw, said straw being thus left in a condition unfit for feeding purposes because of the presence of such beards, dust, and dirt, and the value of the straw is thus depreciated. Again, in using such stackers in a barn dust and fine filth will be blown into every nook and corner of the building, which is very objectionable to a progressive farmer and renders pneumatic stackers unpopular for barn threshing. Again, it is often desired to separate the chaff from the straw and deliver said chaffl clean and free from beards, dust, and dirt, in which condition it becomes quite valuable for feed.

The object of my said invention is therefore to provide certain improvements in the construction of parts and arrangement of details of threshing-machines using the pneumatic stacker,whereby the straw is not only freed from the chaff, beards, and light filth, but the chaff also may be cleaned from said beards, dust, and filth when desired, and also whereby the straw, chaff, and dirt may all be discharged together when separation is not desired, all as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings, which are made a part hereof, and on which similar reference characters indicate similar parts, Figure 1 is a longitudinal sectional View through the tail end of a threshingmachine to which portion of the machine my improvements are confined Fig. 2, a horizontal section through the same looking downwardly, as indicated by the arrows, from the dotted line 2 2 in Fig. 1; Fig. 3, a transverse vertical section looking in the direction indicated by the arrows from the dotted line 3 3 in Figs. 1 and 2; Fig. 4, a top or plan view of the removable partition which divides the straw-stacker from the chaff-chamber; Fig. 5, a rear elevation of the same; Fig. 6, an end elevation looking in the direction indicated by the arrows from the dotted line 6 6 in Fig. 5; Fig. 7, a top and side view of a fillet or door for closing the space under the of the dust-discharge when desired and Figs.

9 and 10 views similar to Fig. l, showing modified forms of the invention.

In said drawings the portions marked A represent the frame of a threshing-machine; B, the straw-rack; C, the tailings-riddle; D, the fan-casing of the straw-discharger, E, the fan-casing of the dust or dirt discharger; F, conveyer-arms, and G the partition separating the straw-chamber of the pneumatic stacker from the chaff-cleaning chamber.

The frame A, straw-rack B, tailings-riddle C, and stacker-casing D are or may be of any appropriate construction, a pipe Dl running from casing D and connecting with the usual stacker-pipe, through which the straw is discharged. The fan-casing E is mounted 0n the opposite side of the separator and has a discharge-pipe E attached thereto, through which the dust, &c., may be discharged to any point desired. The discharging-fans D2 and are mounted in the casings D and E, respectively, and on the same shaft l, which is appropriately driven.

he conveyer-arms F are of the form and construction shown in my Patent N o.

611,383, and need no special description' herein, being used to convey the straw into the discharger-casing D.

Agitating-fingers F are mounted on a hub fon shaft l, adjacent to the entrance to discharger-casing E for the purpose of keeping the heavy dust agitated or stirred up around the entrance to the casing E, and thus in better condition to be drawn into the discharger.

The partition G is of the form shown in Figs. 4, 5, and 6, its main portion extending across the machine just at the rear end of the straw-rack B, its lower edge fitting closely to and supported by the board c under the rear end of the chaff-riddle C3. A flexible section G extends from a cross-bar c, secured on the top of said partition Gr and joins to the rear end of the return-bottom B under strawrack B, thus completely cutting oil all communication between the rear end of the chaff- -chamber and the passage or chamber into which the straw is discharged from the rear end of the straw-rack B. One end of said partition G extends to the side of the machine adjacent to the strawdischarger and the IOO IIO

other end turns approximately at right angles a short distance from the opposite side of the machine and extends to the rear side of said passage or straw-chamber, leaving a passage-way to the dust-discharger from the said cha-chamber. Said passage -way is covered by the inclined top G2. A slot g is formed in the end portion of said partition to pass over shaft 1, and the fillet G3 (shown in Fig. 7) is provided to fill said slot below said shaft when the partition is in place, a button g being provided to hold the same in place, as will be readily understood. On the rear side of said partition G are mounted hangers 2, in which is mounted a shaft 3, on which are conveyer-arms 4, similar in form to conveyerarms F on shaft 1, but reversely arranged. Said shaft has a sprocket-wheel by which it is geared through the medium of a sprocketchain 5 to a similar sprocket-wheel on shaft 6 of reel 7, which in turn is driven from the driving-shaft in the usual manner. Said con veyer is for the purpose of agitating the dust and dirt which collects in the front of said partition and conveying it into the passage where it will be drawn into discharger-casing E. At the rear end of tailings-riddle G is a chaff-riddle C3, which extends beyond the return-bottom C When said chaff-riddle is not used and the chaff is to pass with the dust, the riddle must then be covered by a corrugated board C2, as shown in Fig. 1 ,.which will y be presently more fully described.

The operation is as follows: rlhe parts being arranged as in Fig. 1, the straw will fall into the chamber behind the partition G from the top of the straw-rack B and be discharged through the stacker-tube in a clean condition. The grain, chaff, and dust all fall through the straw-rack onto the bottom B',

the grain being cleaned and separated fromthe chaff and dust in the usual or appropriate manner. The chad and dust are finally brought back over the board C2 by the blast from the cleaner-fan and the motion of the tailings-riddle C and drawn into discharger E and discharged through spout E, while the tailings rop through said riddle onto the return-board C and are carried back to the tailings-elevator (not shown) and returned to be rethreshed in the well-known manner. When it is desired to clean the chaff that it may be used for feed, the board G2 is removed from the chaff-riddle G3, when, by reason of the discharger E2 being of slightly greater 'capacity than the cleaner-fan, (not shown,) a

gentle current of air is caused to pass upwardly through the chaff-riddle C3, which will carry the dust, beards, and fine dirt along to dischar er E, by which it will be discharged throug tube E', while the clean chaff is permitted to fall through said riddle under the machine in pro ery conditionto be fed to stock. When it is esired to discharge the straw, chaff, and dust together, as when neither the straw or chaff are to be saved for use requiring them to be clean and the threshing is being done out of doors where the injury to buildings from the dust will not result, then partition G is removed by unfastening it andlifting it out of the machine through door A. The eye of the casing E is then closed by the disk A2, which is formed in two parts with an opening for shaft 1, around which it is adapted to fit and completely close said eye, as will be readily understood. By use of the straw and chaff cleaner such as described the machine is adapted, while using the pneumatic straw-stacker, to overcomeall the enumerated objections to such stackers, and the chaff may be thoroughly cleaned to adapt it to be used for-feed and the straw cleaned and made more valuable for feeding or any desired use. In the arrangement shown in Fig. 9 the same resultis accomplished by the arrangement of the discharger-fans on opposite sides of the transverse partition P, the straw going into discharger 1() and the dirt into discharger 11 and being discharged through appropriate pipes, as will be readily understood.

In Fig. 10 ythe discharger-fans are arranged on a vertical shaft 12, the casing 13 of the upper discharger 14 being open at its top and arranged to receive the straw from the strawrack, the space between them being closed by A a flexible partition 15 and the lower casing 16 being arranged to receive the dirt and chaff from off the tail end of riddle 17, to be discharged by discharger 18. These and other modifications in the arrangement of parts may be substituted for the arrangement shown in the principal views, if desired, as will be readily understood, without departing from my invention.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a threshing-machine, the combination of a vibratory straw-bottom the artition having a flexible section connecte with the rear end of the vibratory straw-bottom and dividing the space behind completely from the space in front thereof,- a discharger connected with each chamber on each side of said partition and means for directing the material into each of said dischargers, substantially as set forth.

2. In a threshing-machine, a separatingcasing divided -by a cross-partition near its rear end, the upper edge of said partition being connected to the straw-bottom by a flexi- IOO IIO

ble section, a discharger communicating with the chamber in front and also one communieating with the chamber in the rear of said partition, and means for directing the matesite sides of the separator, one adapted to receive the material discharged over the end of the straw-rack and the other to receive the material discharged over the end of the tailings-riddle, the two being completely separated one from the other by a partition or casing, substantially as set forth.

4. A' threshing-machine comprising two dischargers, one being arranged to receive the straw from the straw-rack, and the other the material which passes over the end ofthe tailings-riddle, and a removable board over the end of said tailings-riddle, substantially as set forth. 1

5. In a threshing-machine, the combination, of the two dischargers one arranged to receive the straw from the straw-rack and the other the material passing over the tailings riddle, said tailings riddle being provided with a removable board at its rear end, said dischargers being separated one from the other, substantially as set forth.

6. In a threshing-machine, a partition removably mounted in the rear end of the separator, a discharger communicating with each side of said partition, and a removable door for closing the entrance to one of said dischargers, substantialb7 as set forth,

7. A straw and chaff cleaner having a dust and air tight partition separating a pneumatic straw-stacker and a grain-separator and chaff-cleaner, the stacker arranged on one side of the machine and adapted to receive the straw from the straw-rack, the chaff-cleaner arranged to discharge from the opposite side of the machine and adapted to receive the chaff and dust falling through said straw-rack, and a discharger connected with each chamber and adapted to discharge its contents, substantially as set forth.

' 8. A straw and chaff cleaner for threshingmachines with pneumatic stackers comprising a chamber arranged to receive the straw from the straw-rack, the pneumatic stacker connected with said chamber, another chamber arranged to receive the material passing over the end of the chaff and tailings riddle, and a discharger connected therewith, said two chambers being completely separated one from the other, and a conveyer in each chamber adapted to convey the material to the dischargers, substantially as set forth.

In witness whereof I have hereunto set my hand and seal, at Waynesboro, Pennsylvania, this 8d day of December, A. D. 1901.
